Caching Aerials in a different Coordinate System

Good morning:

I have a strange problem to deal with caching of the aerials.

All our Aerials are stored in SDE in State Plane WKID-2237 (NAD_1983_StatePlane_Florida_West_FIPS_0902_Feet). But we are planning to publish all our map services in WGS_1984_Web_Mercator Auxiliary Sphere (WKID-102100) to match up with the ArcGIS online/Bing maps.

What is the best way of caching the aerials in a different coordinate system than that of its source in storage? Transforming it and then storing it is being restricted- partly due to space limitations.

Can I do this by just changing the coordinate system in the Map Document to WKID 102100 and caching it without any Transformations? Are there any pitfalls with this approach?

Please suggest.

Thanks in advance
Ann

Am I the only one who came across such an issue? ESRI- any help?

Hi Ann,

You should be fine just changing the coordinate system of the data frame in the MXD, publishing, then caching. You can also specify a datum transformation in the data frame properties that will only apply to the MXD.

The only drawback might be a small increase in caching time since the data is being reprojected, but once it's cached there should be no performance impact.

Hope this helps.
